Abstract

A valve or ball reversal orifice (10) provides a first flow restriction to a material flowing through the ball reversal orifice and a second flow restriction when the material reverses flow direction. The valve includes a housing having at least first (20) and second walls (22) that define a cavity (18) therein. The cavity is configured such that a cross-sectional area of the cavity taken perpendicular to a longitudinal axis of the cavity decreases from the second wall (22) to the first wall (20). A first port (32) is provided in the first wall for allowing material to enter or exit a cavity, and a second port (34) is provided in the second wall for allowing material to enter or exit the cavity. A flow restrictor, such as a ball (30), disposed in the cavity and is movable between a relatively large portion of said cavity and a relatively small portion of said cavity to provide different flow restriction depending on the direction of material flow through the cavity.
